Wimbledon organisers have apologised after the electronic line-calling system was turned off in error at a crucial moment in Sonay Kartal’s match on Centre Court.

The British No 3’s opponent, the 34-year-old Russian veteran Anastasia Pavlyuchenkova, accused the All England Club of home bias and said a game had been stolen from her when the AI-enhanced technology missed a call.
